💅 die_get_var_range(9) — the Kernel API Manual, bestie edition ✨

okay so real talk: this is die_get_var_range, and yes the manual name is <rainbow>Kernel API Manual</rainbow> because that's literally where we live now 🎀

---

🌸 NAME 🌸

die_get_var_range — get the byte offset range of a given variable DIE 💖

---

✨ SYNOPSIS ✨

int die_get_var_range (Dwarf_Die *sp_die , Dwarf_Die *vr_die , struct
strbuf *buf );

like, that's the whole signature, no cap 🫶

---

🎀 ARGUMENTS 🎀

• sp_die — a subprogram DIE. the function-side of the situation, if you will 👑
• vr_die — a variable DIE. the variable in question, main character energy 🌟
• buf — a strbuf for the type and variable name and the byte offset range. it's holding all three, she's booked and busy 😭

---

💜 DESCRIPTION 💜

so what she does is: she gets the byte offset range of vr_die and stores it in buf, formatted like this ⬇️

"<function_name+[NN-NN,NN-NN]>"

that's it, that's the vibe 🦋 honestly obsessed with how tidy that looks.
